I'm playing on a 4k tv and was initially having resolution issues where my screen was being cut off. I Have resolved those issues but now all my font and menus aside from character names are incredibly tiny and I cannot seem to figure out how to fix it. Could someone please help with this? I'm including a link to a screenshot so you can see what I am talking about. https://imgur.com/a/3CoyuVG

If you fire up the launcher, click the 4k profile, click the pencil down the bottom to edit, click the window tab on the left, and find menu size. Window size for 4k should be 3840x2160, which is what I have. However I have menu size set to 3072x1628, which makes the menu's and chat and pretty much whole UI larger. If that's not large enough you could even do 1920x1080 which would simulate 1080p menu's on your 4k tv.

Thank you! That did the trick!

To fix tiny fonts and menus in Nasomi on a 4K TV, adjust the Overlay Graphics Resolution and Background Resolution to a lower setting (e.g., 1920x1080) in the FFXI Config Tool and set the Font Size to Standard or Large. Additionally, tweak Windows DPI scaling by right-clicking the Nasomi launcher, going to Properties > Compatibility > Change high DPI settings, and overriding DPI scaling to Application. Restart the game after applying these changes to ensure the settings take effect.
